More than 100 people fleeing violence in a remote Northern Territory community have now arrived in Adelaide after leaving a secret location in Alice Springs.

Last week, dozens of people rioted in Yuendumu, 300 kilometres north-west of Alice Springs, when an ongoing feud between two family groups escalated following the death of a man.

Several cars were torched, a number of houses were damaged and police issued a travel warning.

The group of people now in Adelaide initially took shelter in a police-protected safe house in Yuendumu.

They then moved to a secret location in Alice Springs and the ABC now understands a bus carrying the same group of people has arrived in the northern suburbs of Adelaide.

A spokesman for the South Australian Minister for Families and Communities says the Government has made arrangements for their arrival.

He says the group includes 34 children and they are likely to need housing, health and education support.

'Crisis situation'

South Australia Premier Mike Rann says welfare agencies were given very little notice and have worked rapidly overnight to prepare for their arrival.

He says the Government has been told some people on the bus may require urgent medical care.

"My Government's priorty will always be the safety and wellbeing of these people who are obviously in a crisis situation given that they've had to leave the Territory to find safe haven in the south."

Northern Territory Police say they advised people from Yuendumu not to leave the community and have had nothing to do with them since they left.

Police say they have arrested most of the offenders involved in last week's riot and have stationed extra police in the community in an effort to keep peace between families.

"We're in contact with the elders in the community because our main aim is to try and assist with mediation in the community," Acting Senior Sergeant Shaun Gill said.

"In terms of the actual people who have allegedly gone to Adelaide, no I haven't [spoken to them]."

Northern Territory Chief Minister Paul Henderson says he is extremely disappointed someone has independently organised the transport of the group to Adelaide.

He says their transfer to South Australia is in direct contradiction to police advice.

"Police are certainly very disappointed that this has happened because they were actually working with people in Yuendumu to resolve the issues there and then all of a sudden a number of key people disappeared overnight on a bus," he said.

"Whoever has done this has not consulted with police, has done so independently and needs to have a good hard look at themselves."
